In one memo Darroch reportedly wrote to senior politicians in Britain, the official stated, “We don't really believe this administration is going to become substantially more normal; less dysfunctional; less unpredictable; less faction riven; less diplomatically clumsy and inept.”

Darroch also reportedly warned British officials that the president’s “career could end in disgrace” and claimed without evidence that Trump could have been indebted to “dodgy Russians.”

The memos reportedly date back from 2017 to the present. A government official in the U.K. confirmed to CNN that the memos leaked to the Daily Mail are “real.”

A statement from the British FCO seen by CNN said, "The British public would expect our Ambassadors to provide Ministers with an honest, unvarnished assessment of the politics in their country."

“Their views are not necessarily the views of Ministers or indeed the government. But we pay them to be candid. Just as the US Ambassador here will send back his reading of Westminster politics and personalities,” the office continued.

"Of course we would expect such advice to be handled by Ministers and civil servants in the right way and it's important that our Ambassadors can offer their advice and for it remain confidential. Our team in Washington have strong relations with the White House and no doubt that these will withstand such mischievous behaviour," the office added.
